AC joint injury. Out to me @ 9538793!

Hi Doctor, I'm Ravi here. Recently, I met an bike accident & now suffering from AC joint injury. I have consulted the Ortho doctor & didn't specified about the type of AC joint but advised me to keep my shoulder in immobilizer state for 4 to 5 weeks & prescribed the medicines for 5 days initially. But even after 15 days from an accident still I have an pain & I couldn't able rotate my hand up/down & only can able to do if someone's helped me. Even, I have consulted the doctor few days back but still he is asking me to continue the same for another one month. Currently, I have not been advised to take any capsules or medicines only just wearing arm pouch. I'm scared, will it be heal automatically without taking any medicines by just wearing the arm pouch since not found much improvement from pain & as well as rotation from past 15 days. Request you to please advise on my issue. I have all my reports handy like x-ray, prescription & other reports. Request you to reach out to me @ 9538793
